<P>PROBLEM TO BE SOLVED: To provide a biodesulfurization device of a biogas which cleans a filler layer without aeration while ventilating the biogas even when the filler layer is occluded by generated sulfur etc., and to provide a cleaning method of the same. <P>SOLUTION: The biodesulfurization device includes: a biogas source 5 that supplies the biogas generated in a methane fermentation treatment of organic materials; a tube reactor 2 having a liquid phase part 22 that contains the filler layer 3 maintaining microorganisms that decompose a sulfur content included in the biogas by a microbial reaction, and having a gas phase part 21 above the liquid phase part; water supply means 4, 6, 11, L4, L41, and L11 that supply water in the tube reactor so that at least a portion of the filler layer is in an immersed state; an upper biogas inlet line L2 that introduces the biogas before a desulfurization treatment into the gas phase part; and a lower biogas inlet line L3 that blows the biogas before the desulfurization treatment into the water in the liquid phase part to clean the filler layer by an aeration flow of the blown biogas. <P>COPYRIGHT: (C)2013,JPO&INPIT |
